Personality Upgrade: ChatGPT Learns to Talk Like Us

OpenAI unveils GPT-5.1 conversational upgrade  
OpenAI announced the rollout of GPT-5.1, a refinement of its GPT-5 series aimed at improving the natural flow of conversations. The new release addresses feedback that earlier versions felt mechanical, introducing warmer tones, adaptive reasoning, and customizable personality modes.  

GPT-5.1 comes in two variants: Instant, which provides faster and more accurate responses for everyday queries, and Thinking, which slows down to handle complex reasoning tasks.

• Conversations are designed to be more natural, witty, and human-like  
• Personality presets allow customization of chat styles for different contexts  
• Adaptive reasoning improves performance on complex queries and coding tasks  
• APIs enhanced with developer tools for faster and more efficient applications
